Which object is required to create a Sales agreement?

 A sales agreement is a long-term agreement between a buyer and a seller to negotiate price and volume of products. To create a sales agreement in Salesforce Manufacturing Cloud, you need to have an account object that represents the buyer. The account object stores the information about the customer, such as name, address, contact, industry, and so on. You can also associate a contact object with the account to specify the person who is responsible for the sales agreement. Other objects that are related to the sales agreement are sales agreement product, sales agreement product schedule, sales agreement line item, and sales agreement forecast. References: SalesAgreement | Manufacturing Cloud Developer Guide | Salesforce Developers, Sales Agreements and Forecasting in Manufacturing Cloud | Salesforce Module, Convert Opportunity to Sales Agreements in Salesforce Manufacturing Cloud
